Boost your rental property's value with a home energy upgrade. Leverage tax incentives and grants for cost-effective improvements.

Newer rental properties are built to use very little energy but older rentals often use a lot more. As a landlord, you might think upgrading isn't worth it if tenants are the ones paying the energy bills. Making your property more efficient is always the smart choice, and thanks to a range of government supports, it’s now easier than ever.

Why upgrade your rental property?

  • Upgrading your property's energy efficiency has many long-term benefits. Not only will it raise your property's value but it could also lower your mortgage rates.
  • Being an attentive landlord is crucial for maintaining positive, long-term tenancies. By investing in energy improvements, you will provide your tenants with a warmer and healthier home. With a cosier living space and lower energy costs, tenants will be encouraged to stay longer.
  • Many energy upgrades can be done without much disruption and while tenants stay in the home.
  • Private and commercial landlords can access a range of financial supports for energy upgrades, including SEAI grants, tax incentives, low-cost loans and favourable mortgage rates.

Many banks now offer ‘green mortgages’ for rental properties with a BER of B3 or better. The savings from a green interest rate are significant. According to 2023 research from the Central Bank of Ireland, these mortgages typically see a 0.3% interest rate discount. Over a mortgage lifetime, these discounted rates could save you thousands.
